Comparing insulation thermal conductivity and cost

    I'm currently pricing insulation for house and getting the following prices from two different suppliers:

    Quinntherm 150mm full fill w/ 0.022 w/mK @ €14.62 per sheet
    Cavitytherm 150mm full fill w/ 0.021 w/mK @ €16.26 per sheet

    The overall cost difference is ~ €1k

    My question is if a 0.001 w/mK difference in thermal conductivity is worth the €1k cost saving?

    Which one is interlocked and notched for jointing?
